Abstract

At two sites in the Czech Republic and Slovakia we found plants morphologically intermediate between Carex flacca subsp. flacca and C. tomentosa. Here we present the results of morphological and molecular analyses conducted to test whether these plants are the putative hybrid C. ×danielis (C. flacca subsp. flacca × C. tomentosa). The results revealed a conflict between the morphological characters and molecular markers. Although morphological characters show combinations of characters of the supposed parents and some intermediate characters, molecular markers (ITS, AFLP, trnL-F) indicate that the putative hybrid clearly belongs to one of its presumed parents, C. flacca subsp. flacca. These results refute reports of this hybrid occurring in the Czech Republic and Slovakia.
